​

Answer 1

Step-by-step explanation:

5:3:12

5:3=480

5x:3x=480

8x=480

x=60

12x=12(60)

=720

Answer 2

Answer:

GIVEN

MEN=5

WOMEN=3

CHILDREN=12

LET BE

MEN=5x

WOMEN=3x

CHILDREN=12x

SOLVE

(5x+3x+12x)=480+12x

20x=480+12x

20x-12x=480

8x=480

x=480÷8=60

NOW

MEN=5x=5*60=300

WOMEN=3x=3*60=180

CHILDERN=12x=12*60=720

there were 720 children..
